ABSTRACT

The Memory Validity Profile (MVP) is a standalone performance validity test developed specifically for use with children. Prior research has demonstrated the MVP’s strength in its ease of administration to children with a wide range of intellectual abilities. However, it has been found to lack sensitivity in detecting noncredible performance in select clinical populations using published cutoffs. The current study examines the MVP’s performance in a diagnostically heterogeneous clinical sample and proposes a new cutoff for optimization of sensitivity and specificity. Archival clinical data were examined from 96 participants referred for a comprehensive neuropsychological evaluation (ages 6–18). Receiver operating characteristic analysis was used to assess the discriminative ability of MVP in detecting cases of noncredible performance defined as failures on both the Test of Memory Malingering and Reliable Digit Span. Using published cutoffs, the MVP demonstrated perfect specificity (100%) but suboptimal sensitivity (33.3%). Receiver operating characteristic analysis revealed strong discrimination using MVP Total score (AUC = 0.891 (p < 0.001)) and a MVP Total cut-score of ≤30 resulted in optimal sensitivity (89%) and specificity (63%). Our findings provide additional evidence that published MVP cutoffs may be too lenient to adequately capture instances of noncredible performance and indicate an MVP Total score cutoff of ≤30 may be more appropriate for use with heterogeneous clinical populations.

摘要

记忆有效性配置文件 (MVP) 是一种独立的性能有效性测试，专为儿童使用而开发。先前的研究已经证明了 MVP 的优势在于其易于对具有广泛智力的儿童进行管理。然而，已经发现使用已公布的临界值检测特定临床人群中不可信的表现缺乏敏感性。当前的研究检查了 MVP 在诊断异质临床样本中的性能，并提出了一个新的临界值以优化敏感性和特异性。来自 96 名参加全面神经心理学评估的参与者（6-18 岁）的档案临床数据进行了检查。接收者操作特征分析用于评估 MVP 在检测不可信性能的情况下的辨别能力，这些不可信的性能被定义为在记忆欺骗和可靠数字跨度测试中的失败。使用已公布的临界值，MVP 表现出完美的特异性 (100%) 但次优的敏感性 (33.3%)。接受者操作特征分析显示使用 MVP 总分（AUC = 0.891（p < 0.001)) 和 MVP 总分值≤30 导致最佳灵敏度 (89%) 和特异性 (63%)。我们的研究结果提供了额外的证据，表明公布的 MVP 临界值可能过于宽松，无法充分捕捉不可信的表现实例，并表明 MVP 总分临界值≤30 可能更适合用于异质临床人群。
